how do photons escape the gravity of the sun?

Question

And do any other particles escape? And how?

In: Chemistry

Answer 1

Photons do experience the effects of gravity, but they can escape the sun’s gravity because they are incredibly fast allowing them to keep going even though the sun’s gravity tries to pull them back. More intense gravity (such as a black hole) is so powerful that even a photon‘s speed isn’t enough to overcome it. While photons don’t slow down as they escape the sun’s gravity, they do lose energy which we can measure. This allows us to know what is happening to stars very far away from us.
